The purpose of this study is to determine if discontinuing statin medications is safe and can reduce the burden of taking numerous medications. We anticipate that people with advanced illness will have less medicine-related side effects and symptoms if statins are discontinued, better quality of life, and no change in overall length of life. But we also recognize that it is important to understand if stopping preventative medicines like statins is safe, and that patients may experience emotional distress and lower sense of well-being when medicines are stopped. This study is designed to answer these questions.
